This is basically just a visual thing, but nothing feels like it has "oomph" behind it.
Every ability feels light and cottony, and in general projectiles look slow.
I really would like to see this game take off, but I feel as if, in it's current state, nothing looks or "feels" as powerful or impactful as it needs. There's no reason to really get excited about an ability cast. Sure, it can be an effective ability, but it just doesn't feel POWERFUL right now.
Just something to consider. Part of this is some sound tweaking, part is some gameplay tweaking, most of it is probably visual. It just feels like nothing hits hard.
